Jeremiah 14:14
Then the LORD said to me, The prophets prophesy lies in my name: I sent them not, neither have I commanded them, neither spoke to them: they prophesy to you a false vision and divination, and a thing of nothing, and the deceit of their heart.

Jeremiah 23:16
Thus said the LORD of hosts, Listen not to the words of the prophets that prophesy to you: they make you vain: they speak a vision of their own heart, and not out of the mouth of the LORD.
